  1. 1. Flowers the Angiosperm Seed Plants Botany 2012 acloutier copyright 2012
  2. 2. Gymnosperms are different from Angiosperms• Angio means “vessel”• Sperma means “seed”• Gymno means “naked”• the seeds of the gymnosperms are exposed• the seeds of the angiosperm are enclosed acloutier copyright 2012
  3. 3. Transportation in the plants xylem and phloem work acloutier copyright 2012
  4. 4. Vascular plants have xylem and phloem to transport water and nutrients• Gymnosperms is a vascular plant • Angiosperms are vascular plants that produces seeds that are not that produce flowers with one or protected by fruit but are hidden more seeds in a woody cone. • Angiosperms make up two classes:• They do not have flowers • Moncotyledonsous (monocots)• Most retain their leaves year round • Dicotyledonous (dicots)• Over 6,000 species in four • Angiosperms make up more than divisions: 80% of all plant species ranging• Conifer from roses to palms• Cycads• Ginko• Gnetophyte• Most gymnosperm are in the conifer division acloutier copyright 2012
  5. 5. Angiosperms belong to the Phylum Magnoliophyta Divided into two classes:• Monocots • Dicots• have one cotyledon • have two cotyledon (seed(seed leaf) leaves)Veins are parallel in leaves • Veins are net like and branchingPollen is generally needed for fertilization, but, root • Pollen is generally and stem divisions can needed to fertilize in also generate new reproducing progeny progeny acloutier copyright 2012
